I agree with the article. If you have something you do not understand word,
you need to 'meet' the word in many different stories or articles.
There are many meaning in a word. One time I did not understand a word 'material'
. I looked up dictionary and it said that mean is fabric. But it didn't make any sense, so I
looked up again with ' reading material '. That mean was something to read.
Finally I understood the word.
I have to read many kinds of article or newspaper. Then I can get to know a word well.
